| Radar- Just sent a PM back, thanks!
bigfatbulldog- Yes, there is a slight power increase (10-20hp depending on the dyno). Backpressure is cut down increasing the efficiency of the engine. Mileage increases are minimal (.5-1.5 mpg) with this mod alone though. The sound is definately impoved.
K9Duramax- Yes, do you want a tip with it?
